YARN REEL Application filed October 2-9, 1923, Serial No.

Our invention relates to improvements in yarn reels or winders comprising a rotatable shaft a stationary member and a movable member especially used in winding up artificial threads such as imitation silk yarns and more particularly our invention relates to the means for locking the said movable member with relation to the stated stationary member.

Yarn reels especially adapted for usein winding imitation silk usually consistof a rotary shaft having rigidly aflixedthereto apair of crossed or spider-like members or radial arms interconnected at their outer ends by longitudinal bars or rods which are located parallel to each other and to the axis of the shaft so as to'form the aforesaid stationary member, that is to say, stationary relatively to the shaft, but adapted to rotate therewitln the reel further comprising a system of similar crossed arms loosely mounted on the shaft to be rockable thereon relatively to the stationary member, and having their outer ends likewise connected by parallel bars or rods.

As is known to those skilled in the art the purpose of the displaceable system of interconnected arms is to have'a means for removing the wound up skein or skeins of yarn from the reel. In reels of the kind hitherto employed the angularly displaceable system of arms and winding bars is usually locked in its operative position by means of locking pins in co-operation with an abutment adapted to arrest the system in its operative position. Upon removal of the pin or pins the system can be turned about the shaft as far as required for removing the skeins and thereafter can be turned back, until it will be stopped by the mentioned abutment and can be fixed by the said pin or pins in its operative position for the next winding operation.

The object our invention is to provide a more reliable and efficient means for ar resting and lockingrthe movable system or arms in their operative position. lVith this object in view we provide a single spring arresting and locking device in lieu of the hitherto employed two contrivances and as far our knowledge goes, springs or any other yielding locking means have never been used heretofore and are broadly new in connection with yarn reels of the kind set fortha B WZNIDER.

671,564, and in Germany September 8, 1923.

In accordance with our invention the stopping and locking device comprises a spring made of acid-proof material and of a particular shape adapted to ensure the, double result of locking the movable system in its operative position and at the same time acting as a means for limiting the rotary movement of the system. To this end the spring is given a double bend to form a seat for a locking lug or nose to engage therein, and is further bent outwards to provide a stop which the said nose cannot overcome when catching or engaging into the seat.

In the accompanying drawing a single embodiment of our invention is illustrated by way of example. Figure 1 is an elevation of the reel; Figure 2 is an end view thereof 7 with the two winding-up systems or arms in their operative positions; Figure 3 is a similar view with the systems or arms collapsed or in position for removing the skein or skeins from the reel prior to a next winding operation; Figure 4 is a fragmentary crosssection on theline GD of Figure 5 on an enlarged scale; Figure 5 is a cross-section on the line A-B of Figure 4 with the movable system or arms locked in the position illustrated in Fig. 2; and Figure 6 is a crosssection as in Fig. 5, but with the parts in the position shown in Fig. 3. y

In the embodiment shown the reel comprises a rotary shaft A with a system of stationary arms S rigidly attached to said shaft and carrying four bars or rods L in parallel relationship with respect to each other and to the shaft. Movably mounted on the shaft 90 a is another system of arms S carrying two bars or rods L only, as usually in reels of the kind in question. The six bars or rods L and L are-arranged in such a manner that when they are in operative position, as

shown in Fig. 2, they form a regular *hexa gon. Some of the bars or rods, preferably those of'the movable system may be pivotally connected or hinged to the carrying arms in order to facilitate the tilting movement of too the arms S for the removal of the 'skein or skeins. In most cases a single bar or rod L properly hinged to its carrying arm, as shown in Figures 2 and 3, will answer the purpose well.

The contruction of a reel as hereinbefore described is old. -We shall now proceed to explainour improved locking device with 'bentontwards, as at (1., a

reference to the drawin s, in particular Figures '5 and 6 thereof.

On the inner face or" one of the two stationary members S a lug or nose N is provided and-on the oppo="te side or face of the adjacent movable member S a spring F is mounted with suiiicient play to allow the said lug l to engage in a seat it formed in the spring by bending the same inwards and outwards. Both the lug and the spring may be made of acid-prooi material, preferably of acid-proof steel. In order to prevent the movable system or member S from turning, when pulled back into the operative position, over and beyond the said position shown in Fig. 2, that to say, to retain the lug N within the seat R, the spring is further e r and ,6, to form a stop or abutment for the body of the lug to engage therewith when properly seated in the seat "R, as will be readily understood from The winding-up operation being finished, the skeins of wet, shrinking yarn are to be removed from thereel and to this end the system ormember :5 is to be turned about the shaft from the position shown in Fig. 2 to the position illustrated in Fig. 3. This may be done by manually forcing one of the two bars or rods L towards the adjacent bar or rod L or the stationary member, as in Fig. 3. As the top or the lug l\ is rounded or conical shape fitting snugly into the correspondingly shaped seat R, and the spring readily yields under the forcing ac- -tion, the lug W111 so easily disengaged from its seat to allow the member S to be turned into the position shown in Fig. Simuh taneously ther h the h g d bar or rod that we do not limit ourselves thereto, but

hold :ourselvesat libertr to make such departures therefrom fairly'tall within the spirit and scope of our invention.
